I will follow this thread with interest as I was asked to do a 35,000sq.ft. scan the other day. It took 2 hours just to walk around the property... crazy.
I wrote to Matterport support directly to get their thought on how to deal with this... still waiting for them to reply(as often these days).

I'm having the same issue with Matterport support these days. I have left several voice messages and sent numerous e-mails but to no avail. Perhaps they're growing too fast and can't keep up with demand. I've seen this time and time again in the technology world.

Thanks Dan. Although, 7,000sq.ft. and 25K/35K sq.ft. are on different another-level levels!
To be honest, walking this property, I think it will be hard to keep it under 200 scans PER FLOOR! (times 3 floors)...
The project is on hold for now on my side (which is actually a good think considering the technical difficutlies I am sure I will face)...

As well, I'm looking forward to this thread and learning more about camera capabilities & limitations and this forum's real experiences in terms of scanning larger then normal spaces i.e.ceiling height, room size,etc.

With goal of trying to define and specialize in sports applications i e. scanning sports arenas for universities, I'm trying to better determine camera capabilities.

There really shouldn't be any restrictions or limitations with this technology. When one purchases a DSLR or a professional camera i.e. Red, Alexa, Sony etc they don't come with any obstacles other than limited storage capabilities which are in the form of some sort of hard drive or SD card. This is a cloud based subscription, no hard drives required.

Also, when I pull a video file (100 hrs at a time) into my editing suite it doesn't have any restrictions. The Matterport App should perform the same without any issues.

You're talking apples to oranges here, the MP camera is taking tens of thousands of reference points for it mesh every time it does a sweep which no one is aware of. The background technology of the MP camera has no comparison to a static snap on a DSLR or a video shot on Red or any other digital camera. With both of these technologies “what you see is what you capture”. You can hardly say that with MP as there is a tremendous amount of processing going on in the camera and the iPad to do the primary orientation of the capture.

Many of us have captures well over 200 scans but the issue is the loading of the SC which can take longer the one would like if you exceed this recommended number. Often we shoot many more scans an then in post edit them down as we wanted to make sure we captures to look and feel of the location.

I just published 170 scan job and it loads with no issues. I published it so i can decide which scans i will delete to try and get it down to 100. is this the right way to do it? Without publishing it, its impossible to decide which are the best scans that you dont mind deleting.

That is the right way to do it. I would always suggest duplicating the model before you start to delete the scans as you have a your original to fall back on and reduplicate if needed. On one job I ran into trouble with a very difficult multi-storey glass stairway and I had to upload the job 6 times before I solved the problem. Once the SC was correct I deleted the other SC's from my My-Matterport account. This take time but it’s the safe and correct way to get the SC perfect.

Thanks! Would you mind taking a look at this before i deliver to the client? its a mess. i still need to trim, and delete a bunch of scans. most areas have both day and evening views. I am deciding which i like better. Need to also return to the property tomorrow to scan the rooftop, up the spiral staircase on balcony. the exterior came out better than anticipated.

This is a tough one as you already know you have way to many scans. I’m sure that this was partially down to alignment issues when you were shooting in the daylight and then in the night. Sunlight can play a real problem with scans bleeding into other rooms or opening up holes in the floor or walls. You have this issue in a closet in one of the bedrooms as you can see the scan points through the wall.

You also have the issue with the closed glass door but can see the scan points outside which you can click on and presto it's not night time. I would ask the client do they want to present the house in the evening or in the day. If they pick evening you have all of these great exterior shots you can use. I would duplicate the model once the client has decided and eliminate all of the window shots that either show daylight or night and then pickup shooting from there.

On other option is to offer the client two versions of the SC one in the day and the other in the night which the customer my like. This will give you two models for you to showcase to you future clients. Make sure that you tell any future clients that a daytime and night time SC are an extra cost.

Thanks! Yeh. this is a tough one. the sun sets right in the backyard. There is only like 40 mins of "prime-time" scanning. So, i shot the whole house during the day and then st sundown started to scan all of the exterior and then scans with exterior view. I am pretty sure i am going to go with the evening version. So, when you go near the doors it will get dark out. nothing i can really do about that. Great idea on creating 2 models though... thanks. How would you trim? On the second floor, you can see the exterior walls in the dollhouse view. Nothing i can do about that, since i am also shooting outside? If i trim along the wall, then i will eliminate the exterior walkways and pool from the dollhouse feature. where would you trim?

Don't worry about triming the customer will be wow with the VT and they won't even think about how the dollhouse looks. Make sure you go back and shoot that one exterior door with it being open with a night view so you can walk outside.

Good luck and let me know how it turns out as you've done a great job.
